Can Phalaenopsis orchids be disinfected with potassium permanganate? There are rules about how much to trim the roots

Visiting flower markets in different regions, the common point of most shops is that they all stock this darling, the "Phalaenopsis orchid." At the same time, the variety of styles to choose from is beyond imagination, from mini types to large flowers, there is everything you could want, and they are extremely lively and graceful. However, to protect their beautiful appearance, there are many secrets to pay attention to in terms of care.

Recently, a flower friend left a message in the backend asking: I previously read some posts shared by skilled growers about Phalaenopsis care, and they said potassium permanganate and plant ash could be used to sterilize and disinfect Phalaenopsis. So I did that, but after soaking I did not rinse it with clean water. I do not know whether operating this way will cause problems? Also, when I dealt with the roots, I could not bear to cut too much.

Afterward, when I replanted it back into the pot, I planned to use all sphagnum moss as the growing medium. After planting, do I need to change the flower pot? Right now my flower pot has a diameter of about 12 cm. After it is done, do I need to water it thoroughly once?

Regarding the flower friend's question, it is recommended that you first trim the rotten roots and decayed roots of the Phalaenopsis properly. After trimming, let it dry in a ventilated place for one day. By the way, disinfect the scissors used for trimming in advance. After doing this, it is not recommended to use other medicines.

In addition, you mentioned that you could not bear to cut too much. Actually, it does not matter, because even if all the roots are cut off, this Phalaenopsis will not die. The remaining roots mainly serve to anchor the plant and do not have much effect on its normal growth. If after trimming there are not many roots left, then change to a small 2.5-inch pot to plant it. If you plan to use sphagnum moss as the growing material, then after planting it, absolutely do not water it again.

Under normal circumstances, after about three weeks, small bud points will emerge at the root positions. If you use a transparent flower pot, after about one month you will be able to see new roots growing along the side of the pot. However, during this period you must give it moderate light; a spot near a window with good light at home is fine. Growing Phalaenopsis requires patience; this is not something that can be rushed. Just observe it more every day. There is nothing else to pay attention to; simply wait quietly for it to slowly grow well.
